PAINT PAIL AND CLAMPING RING THEREFGR.

Application filed June 12, 1924. Serial No. 719,540.

To all whom it may concern:

Be itknown that T, GEORGE E. MITTINGER,

acitizen of the United States, residing at Cleveland, in the county of Cuyahoga and l State of Ohio, have invented certain new and useful Improvement in Paint Pails and Clamping Rings Therefor, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in paint pails and clamping ring therefor and it pertains to certain improvements in the manner of providing a detachable closure for one end of the pail and the manner of fastening the closure to the pail. H

The present invention is an improvement over the construction shown in my pending patent application Serial No. 695,466, filed February 27, 1924 and entitled Paint pails.

One of the objects of my present invention is to provide the top of the pail or container with an outwardly extending flange, and the cover of the pail with a central depressed portion having an outwardly extending flange, placing a gasket between the pail and cover flan es, and surrounding the said flanges wit a clamping ring having means for drawing the ring inward to force the flanges together and thereby compressing the gasket, thus making a liquid tight closure for the pail.

Another object of the invention is to provide a paint pail having a quickly attachable and detachable top closure which is so constructed that all of said closure and its fastening means are within the vertical plane of the side walls of the pail.

Another object of the invention is to provide a ring for clamping the top on containers or the like in which the ears or lugs for receiving the bolt for drawing the ring together are formed integral with the ring.

Another object of the invention is to provide a ring which is provided with ears or lugs formed integralwith the ring which are a double thickness of metal.

Another object of the invention is to provide a ring of the character described which is very simple and cheap of construction and highly eflicient in operation.

Other novel features of construction and improved results of the invention will appear in the following description.

Inthe drawings:

Figure 1 is a fragmentary view in elevation of my improved ring before the ring or lug ears are formed.

Figure 2'is a fragmentary view in elevation showing the first operation upon the ring to form the lugs.

Figure 3 is a fragmentary view in elevation showing the two ends of .the ring drawn together upon the top of a container.

Figure 4 is a vertical sectional view taken on the line H of Figure 3.

Figure 5' is a fragmentary perspective view showing the manner in which the ring or lug ear are formed.

ll am aware that various forms of construction for closing the open end of a paint pail or the like have heretofore been made. I believe however that the invention described and set forth hereinafter is of a specific construction differing from the prior art.

In the drawings: A represents the ring, B the pail or container body and C the container head or cover.

Referring now to the drawings, 25 is the body of the pail or receptacle which may be made in any desired shape or size depending upon the use to which the pail is to be put. I have preferably designed the pail for use as a container for paint.

In my present improvement the upper end of the pail body is curved inward, forming a U-shape bend as shown at 17, then upwardly and outwardly to form a flange 18.

The cover C has a central depressed portion 19 while its upper edge extends outwardly to form a horizontal circumferential flange 20. v

Attention is directed to the fact that .the

inward curve 17 at the upper end of the pail body is considerable in extent so that the outer edge of the flange 18 is in a vertical plane wholly within the vertical plane of the pail body portion 25.

An endless rubber ring or gasket 21 which is flat in cross section is laced between the flanges 18 and 20 of t e pail and cover respectively.

The clamping rin A is V-sha "ed in cross section comprismg t e upper wa l 6 and the lower wall 7. .The V of the ring is formed by having the upper and lower walls meetat an acute angle as at 8.

Adjacent its ends the top wall 6 is cut or sawed as at 9. This cut is the complete width of the wall and ends at the point 8 vll.

where the top wall meets the lower wall. The cutting or sawing of the top wall of the ring is shown in Figure 1 of the drawings,

lower wall 7 of the ring thus forming two thicknesses of metal. A hole 11 is then drilled through the double thickness, of metal adjacent the ends of the ring. These walls are later to receive a bolt 12 provided with a nut 13.

The next step in respect to the forming of the ring ears or lugs is shown in Figures 3, 4 and 5 of the drawings. This step consists in bending the two walls of the ring ends sharply downward as at 14 intermediate the length of the upper wall 10 to form the vertical lugs or ears 15. It will be seen that the openings 11 are in these lugs or ears.

Tn assembling the head and ring upon the receptacle the gasket 21, is placed between the flanges 18 and 20 of the receptacle body and head. The clamping and compressing ring A is then placed in position. lit will be seen that the outer edges of the receptacle and head flanges 18 and 20 respectively are embraced within the V- shaped openingformed between the upper and lower walls of the ring. The bolt 12 is then inserted through the openings in the downwardly extending lugs or ears 15 of the ring and the nut 13 tightened until the ring is firmly in place and the flanges of the recountry it is necessary that the pail be so constructed that none of the closing or fastening parts of it extend beyond the vertical plane of its body portion. In my improved construction it will be seen that the inward bend 17 in the pail body is of a depth sufiicient that when the clamping ring is in place the outer edge of the ring 'is within the vertical plane of the pail body. In

addition to complying with the shipping regulations this construction is advantageous as it does away with any extending edges which might bum other articles during' shipment which might ossible, cause damage to the pail. Attention is directed .to the fact that there is no sealing whatever ar ssaaccomplished between the vertical wall 26 of the cover and the curved portion 17 of the container.

If desired the pail can be provided with a handle so that it may be readily lifted or carried about.

The pail closure constructed as herein de scribed is very readily and quickly applied making a liquid tight joint with the upper end of the pail, and the closure is as readily removed from the pail. This makes it possible for a portion of the contents of the pail to be used and the cover replaced to exclude air from action upon the contents remaining in the pail. This makes a very valuable construction because paint is quickly affected by the action of air.

From the foregoing it will be seen that my improved manner of forming the ring and its lugs or ears provides a ring ready for application which is integral in its entirety. The lugs are very strong as they are formed of a double thickness of metal and they are an integral part of the ring. The construction is also very rapid and cheap of manufacture as will be readily apparent. By forming the ring lugs or ears integral T have done away with the necessity of spot welding the ears or lugs in place as shown in my pending application Serial No. 695,466 and have overcome the difliculties and disadvantages of this ring as have been previously set forth.

Attention is directed 'to the fact that the bolt 12 is made of a length to enable the ring to be extended sufficiently to be lifted latterly from the flanges 18 and 20 by lifting one edge of the ring free from the flanges. The V-shaped ring can then be readily removed from the container and the cover and can, in the same manner, be placed in an embracing position ready to be clamped into the position shown in Figure 3 of the drawings.

Attention is also directed to the fact that the nut 13 of the clamping bolt 12 of the ring is locked in place due to the fact that the squared sides of this nut engages the top portion of the ring ears and holds it from rotating. To loosen the ring it is necessary to turn the bolt 12 in the nut The clamping or fastening ring constructed as herein described is readily and rapidly applied upon the upper end of a container and is as readily and re idly removed from the container. In addition the ring forms a very secure and strong fastening for the container head.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

'1. A metallic pail having its top curved inwardly and then outwardly forming a flange, a cover having its periphery formin a horizontal flange, a gasket between, sai

pail.

amuse flanges, a V-shaped compressible ring embracing said flanges, the upper and lower walls of the ring adjacent the ring end crimped together and bent downwardly, said downwardly bent portions of the ring provided with means for reducing the size of the ring to compress the pail and cover flanges together upon the gasket, and said flanges and ring positioned in a vertical plane wholly within the diameter of the 2. In a device of the character described,

' a ring having upper and lower Walls, and

, the upperand lower walls at the end of the ring crimped together and bent downwardly to provide lugs, for the purpose described.

3. In a device of the character described, a clamping ring having upper and lower walls forming between them a ll-shaped channel, the upper wall of a length cut and crimped downwardly uponthe lower wall adjacent the ring ends, and the double thickness of metal thus provided bent downward- 1y intermediate its. length, for the purpose described.

4. In a deviceof the character described, a clamping ring or the like, having upper and lower walls forming between them a V- shaped channel, the upper wall of the ring out across its width at points adjacent the ring ends, the cut portion of the upper wall bent downwardly upon the lower ring wall, an-dthe double thickness of metal thus provided bent downwardly intermediate its length, and the downwardly bent portion provided with scribed.

In testimony whereof hereunto. afiix my signature.
